Hi, I don't understand what you mean by "The Access article contains ACL of site A and site B."

Thanks for reply,

When create an article from Site-A- the option ACCESS contain these access level: public, guest, registered, SITE A, SITE A GUEST, SITE A REGISTERED, SITEB, SITEB GUEST, SITEB REGISTERED.

I would show only SITE A, SITE A GUEST, SITE A REGISTERED for (SITE A) - SITE B, SITE B GUEST, SITE B REGISTERED for (SITE B)

Is it possible?

Thanks

Ok, so if I understand correctly the problem is in Access level field options? 

Then you will need to make new field with correct options - either Select simple or Select dynamic if you know mysql, important thing is that you set it's storage to the exact same settings as in Article Access field.
